HydroLevelControl
Description
HydroLevelControl is a bundle of hardware and software designed to measure, present and control the level of a fluids. Measurement is based on the hydrostatic pressure provided by the fluid above the pressure sensor. Measured pressure value is converted to requested data format, according to inserted data, like fluid density, reservoir surface, etc. The measured value can be used to activate visual alarm (blinking LCD display), sound alarm and two relays. All this can be configured independently.
Take a care that this device can be used only on atmospheric pressure. Installation in over or under pressured environment can permanently damage the sensor and the device!
Background
The device have a pressure sensor, actually a pressure transducer, that is powered with 5 VDC. Dependently of the pressure, it produce a different voltage on output that is measured and converted to a pressure. Based on the fluid density, is possible to calculate the height of the fluid above the sensor. With the known height and the reservoir surface, can be calculated the volume and the mass of the fluid.

Software
HydroLevelControl software is a program designed to read a measured data an to configure the hardware. It communicates with a USB to Serial TTL, where the TTL is on the hardware side. The software can be downloaded from this page for free.
